Trimming pipette tips

I saw Benjamin Judkewitz trim the fat end off of a pipette tip and stick it onto a 1 mL syringe to make a fine tip for the syringe (above). This is handy for precisely…



Nice enclosures

Most project enclosures are cheap and ugly. I challenge anyone to find something from PacTec that Dieter Rams would want in his house.

The following suggestions might not be Rams-worthy either, but they’re…



Raspberry Pi – Arduinolike form and price, but with way more power

RDUINO A



Introducing the Spectrino

The Open Hardware wave keeps rolling: MySpectral recently announced the Spectrino – an Arduino based spectrometer. It’s as barebones as spectrometers go, with the small enclosure containing a diffraction grating, CCD light…



Light field imaging

Light field imaging is a very interesting approach to imaging. The idea is to use an array of microlenses in order to capture light coming from many different angles. By storing this data,…



Microbehunter

Oliver Kim puts out a nice magazine called Microbehunter. It’s a great resource for microscope nerds. I’ve listed a few blog articles below, but actually, the full PDF issues are where most of…



Multimeters with IR temp

I thought I needed a $30 multimeter. But then I saw that for just a few bucks more I could get some more features. This process repeated itself until I ended up buying …



3D Printed iPhone-to-Eyepiece adapters

Thanks go to commenter ybot for this one. They pointed out this handy iPhone-to-Microscope mount iPhone case.

From the pictures, it looks like the prototype was printed on a Makerbot, which isn’t terribly…



Optical recognition of resistor codes

This is an iOS/iPhone app that uses the camera to optically recognize resistor color code bands. I find this interesting because I tried writing something like this one time. I couldn’t sleep at 3am…



MATLAB Mobile for iOS

On the topic of iOS apps, MATLAB has released v3.0 of their mobile app. The most apparent changes are UI usability improvements.

Sensapex piezo manipulators

Sensapex is the new kid on the block for micromanipulators, and theirs have an ultra small footprint with 20mm of travel on 3 axes. Here are some pictures of one of the…



Easy Arduino projects just got even easier

The killjoy afficiando commenters at Hack a Day love to deride as unsophisticated any project that uses an Ardunio (e.g. this thread). The platform has become so popular that, to co-opt…



DIY Heat pad

More cleverness from Taro Ishikawa. Instead of buying a homeothermic heating pad for surgeries (these often cost > $1000), Taro used some basic industrial process control items. He bought his stuff in Japan, but similar items are available from McMaster-Carr in…



Mini oscilloscopes

Seeed Studio repurposed parts for cheap MP3 players and made a production miniature oscilloscope, the DSO nano. I like this small tool and bought one of the first iterations (see…



Laser pointers and quantum mechanics

Laser pointers are handy…
